How to turn off DLSS while run './runheadless -v'

[gujiacheng]

I run isaac-sim 5.0.0 with official docker image. But crashed while executing ./runheadless script as followed:

and I ran Isaac Sim Compatibility Checker then got result PASSED:

[vick-yu]

That's a good question. The NVIDIA A800 GPU is not supported for Isaac Sim because it does not have the RT cores required for real-time ray tracing (RTX). Isaac Sim requires an RTX-capable GPU to function correctly.

We appreciate you bringing this to our attention and will look into improving the compatibility checker tool to be more specific about this requirement.

@gujiacheng could you share your full kit log file?

[vick-yu]

@gujiacheng could you please share the full log from ~/.nvidia-omniverse/logs/Kit/Isaac-Sim_Compatibility_Checker/5.*/? This will help check why the compatibility checker reported PASSED on the A800 setup and whether it is correctly detecting RTX support.
